  • Lead acid storage battery and method of bonding battery cell terminal posts and bushings
    Patent number: 6309429
    Abstract: An improved method of bonding battery cell terminal posts to cover bushings is disclosed. The battery cell terminal posts are made of lead alloy material and the cover bushings are made of solder alloy material having a significantly lower melting point than the terminal posts. The bushings are bonded to the terminal posts by heating the terminal posts and bushings to a temperature above the melting point of the material of the bushing, but below the melting point of the material of the post, to effect a secure and leak proof connection without melting of the terminal posts and with lesser chance for damage to the plastic cover. The plastic cover further includes integrally formed annular mold sections in the form of upstanding bosses which completely surround respective bushings and posts.
